Description
The Siena 1 is a single-watch Siena — a sloped-front case with a beveled glass viewing panel and a suede-lined interior. It is the smallest configuration in the Siena line, sized for a dresser or office shelf. The sloped geometry sets the watch face at a viewing angle rather than flat, which is the line's defining detail and the reason most buyers choose Siena over the cube-form Sparta.
Multiple layers of high-gloss polyester lacquer over wood veneer, beveled-glass viewing front, full suede lining, suede-covered base to protect the surface beneath. Single drive module that lifts out for battery replacement.
Dimensions — 6.5 × 6.0 × 8.3 inches (H × W × D)
Weight — 4.4 lbs

The Rotorwind Movement
Every Orbita winder runs on the patented Rotorwind movement — a motor and gearbox that accelerate a weighted cup to a defined speed, then release it to freewheel and swing under gravity, reproducing the natural arc of a watch on the wrist.
In continuous production since 1996 and used under private label by several of the world's leading watch manufacturers.
- Motion — On-demand oscillation, not continuous rotation
- Drive — Motor and gearbox; weighted cup freewheels after each drive cycle
- Battery life — Up to five years on lithium cells (battery-powered models)
- Operation — Whisper-quiet, inaudible from across a room
- Over-winding — Eliminated by design
- Warranty — Two years, every component
Programmable Movement
The Programmable movement is Orbita's precision-tuned variation — a gearbox-driven, microprocessor-regulated motor with user-set turns-per-day and directional control for watches with specific winding requirements.
Built on the same manufacturing standard as Rotorwind, the Programmable movement adapts to rare and complicated calibers — GMTs, perpetual calendars, and annual calendars — that demand exact specifications.
- Motion — Microprocessor-regulated wind/rest cycle with user-defined TPD (turns-per-day)
- Direction — Clockwise, counter-clockwise, or auto-reversing
- Range — 650 to 1,600 TPD selectable
- Drive — Brushless DC motor and gearbox, microprocessor-regulated
- Power — AC adapter only (no battery option)
- Operation — Whisper-quiet, inaudible from across a room
- Warranty — Two years, every component

Why Automatic Watches Need a Winder
Mechanical automatic watches rely on natural wrist motion to stay wound. When worn daily, the movement of the wearer keeps the mainspring energized and the watch running with precision.
When left unworn, most automatic watches stop within 48 hours—requiring manual resetting of time, date, and complications.
A watch winder ensures each timepiece remains fully wound and ready to wear.
Winding That Mimics the Human Wrist
Orbita’s patented Rotorwind technology replicates natural wrist motion through intermittent rotation cycles and rest periods.
This reduces wear, prevents strain, and maintains optimal winding efficiency.
Precision Control for Every Timepiece
Orbita winders use a microprocessor-controlled system with adjustable turns per day (TPD) settings.
This ensures accurate winding while protecting the watch from unnecessary motion.
Engineered for Silence. Built to Endure.
Every Orbita winder is designed to operate with absolute discretion — preserving both the integrity of your timepiece and the quiet of its surroundings.
